CAMP-STOVE.

Specification of Letters Patent.

Patented Dec. 5, 19M.

Application filed July 19, 1915. Serial No. 40,550.

To all whom it may concern Be it known that I, NoRFLEn'r HILL, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Camp-Stoves, of which the following is a specification. V

This invention relates to collapsible campstoves and has for its object to provide a portable stove that may be carried from one location in a camp, tent, or the like to another without removing the fire therefrom, and, if gesired, without stopping the cooking of ood.

Another object is to provide a portable stove and cooking outfit that mav be readily and compactly packed convenient for carry-' ing or otherwise transporting same from place to place upon moving camp or upon any other occasion.

Moreover, this invention consists in the construction, of parts more particularly described in this specification and set forth in the claims.

In the accompanying drawings forming part of this specification wherein like numbers of reference denote like parts wherever they occur, Figure 1 is a top plan view of the stove of this invention set up for use as a cook stove. Fig. 2 is a view in elevation of F ig. 1; Fig. 3 is a vertical sectional view of Fig. 1. Fig. at is a sectional view on the line 1010, Fig. 2, showing a plan view of the fire-grate, the means for supporting same in hinged relation with the inner wall of the stove and the means for supporting said grate in operative-position within the stove; Fig. 5 is a sectional view on the line 11-11, Fig. 1, showing a vertical sectional view of a side of the stove-body and fragments of parts adjacent thereto. Fig. 6 is a plan view showing the grate folded up against an adjacent side and showing the hinged sides in position preparatory to being folded over upon each other to form a compact package for convenient transportation; Fig. 7 is a. plan view looking at the underside of the perforated portion of the cover shown in Fig. 1, and shows in dotted lines the imperforate portion of the cover associated with said perforated portion in packed relation thereto. and Fig. 8 is a plan View looking at the underside of the imperforate portion of the cover shown in Fig. 1.

The stove body 1 open at both ends may sonstmcted afany'saitable material, such,

arrangement, and combination for instance, as sheet metal, and may be formed into the trlangular shape shown in the drawings. A. plate 2 is provided with a plurality of perforations 3 of any desired shape and any suitable size, said plate being adapted to form a fire-grate within said stove body 1. Plate 2 may be of any suitable shape adapted substantially to conform to the shape outlined by the adjacent inner walls of the stove body 1, and is supported within said stove body in a position spaced away from the ground, floor, or the like upon which the stove is placed by means of upstanding pins 5, shown at 5 and 6 in the drawings.

A. draft-opening 8 of any suitable size and shape may be provided adjacent the base of stove body 1, and said draftppening' may be adapted to be entirely below grate 2, or may be adapted to be partly below and partly above said grate, as shown in Fig. 2, the purpose of said draft-opening being to supply air from without to aid the combustion of fuel upon said grate. Draft opening 8 may be provided with a door 9 of any suitable construction, such, for instance, as the sliding door 9 shown in the drawings slidably mounted in a pair of guides 10 borne by the outer wall of stove body 1 adjacent said draft-opening 8, said door being o-peratively adapted adjustably to cover and uncover said opening to increase or decrease the draft of air to the fire on said grate.

The usual flue-opening 11 may be pro vided in the upper portion of the lateral wall of stove body 1, which flue opening may be located relatively to draft-opening 8 in a position opposite or as nearly opposite thereto as is practicable, as shown in the drawings, and a smoke-pipe 12 of any desired length adapted to communicate with said fiue-opening may be provided, which pipe 12 may consist of an elbow and a straight joint, as shown in the drawings, or may be otherwise arranged in association with said flueopening to accomplish the well-known purposes for which it serves.

Two or more plates 13 and 14 may be provided, which plates together are adapted to form a removable cover for the open top'end of stove body 1. One or all of said plates may be provided with a plurality of perforations, such, for instance, as perforations 15 borne by plate 13 in the drawings, or one or all of said plates may be imperforate as tieiplate it, shown in the drawings, the par two or more vpose being that the top-end of stove bodyl may be provided either with a removable imperforate cover composed of two or more imperforate plates, or may be provided with a removable perforated cover composed of perforated plates, or may be provided with a cover having a perforated portion and an imperforate'portion,which latter form of coveris the one particularly illustrated in the drawings. Byv this arrangement the cover for the top-endofstove body 1 may be so assembled in positionthat when the stove is set up ready foruse, cook- I ing utensils or the like placed upon the cover may either be entirely shielded from the direct flame andheat-rays of the "fire ed from said within the stove, or may be partially shielddirect flame and rays, or one or more ofsaid utensils or the like may be entirely shielded from saidflame and rays I and another or others of said utensils or the like may be partially shielded-from said flame "and rays, depending upon whether imperforate or perforated plates or a com- ;bination of imperforate and perforated plates areused to form said cover, and thus the intensity of the heat applied to said utensils or the like may be regulated and controlled within certain limits.

The adjoining edges '16 of adj a'cen't plates forming said removable cover may be bent or rolled as shown inFigs. 1, 3,7, and8'to provide a reinforcing means to stiffen said plates, and the edges of stove body 1 may extend latthe edges of saidplates adjacent erally beyond said edges ofv said stove body to provide a bearing surface, as shown in Fig. 1, for said edge of said stove body. Said laterally extendingedges of said plates maybe reinforced by means of a head or the like, not shown, or, if desired, said edges may be provided with a downwardly "depending flanged-portion 19, said flange the under surface of a plate forming part of the cover, the flange of sa1d flanged-plate 20 being adapted to depend substantially parallel to said flange'19 in'spaced relation thereto, as best seen in said Fig. 7.

. "One or more specially constructed 'cooking utensils 21 may be provided adapted to be borne suspended against, and with a portion thereof substantially in, contact with, the'outer surfac'eof the lateral Wall of "stovebody 1, as shown'in'the drawings, said utensil comprising a receptacle 22 having a removablelcover 23, sa1d cover-being comshown in the drawings,

convenience ibemgremovably attached to receptacle 22 by-means-of bearings 30.

the shape of back a suitable angle form a hinged lid, the hinged connection of said two parts being spaced away from the rearward side or back of said utensil so that said lid may have clearance to swing open beyond the perpendicular and rest in that position (not shown) with a portion of its outer surface bearing against an adjacent portion of the stove. This construction permits the lid to be swung to fully open position and may be substantially supported in that position resting against an adjacent portion of the stove. The outer edge of cover 23 may be provided with a downwardly depending flanged portion25 adapted to overlap substantially against an adjacent portion of the sides ofthe receptacle 22, when said cover is in place upon the top of said receptacle, thus providing bearing partsadapted to hold said cover rcmovahly in place upon said receptacle. The construction of receptacle 22 may be such that when 'cover28 is in place thereon in'closed position, the plane of the surface of the top of the utensil will slope downwardly on an incline away from the rearward side or back 26'ofsaid' utensil, said back being adapted to fit against the adjacent outer surface of the lateral wall of stove body 1 when said utensil is supported in position for use, as so that the heat within the stove will be readily conducted to said utensil and to its contents.

By means of a hook or hooks 27, utensil 21 may be removably attached to stove body '1 by engaging each hook'27 in a slot 31 borne by said stove body, as shown in the drawings, whereby said utensil will be suspended with its back 26 substantially resting against the outside of said stove body.

Aremovable bail 29 may be provided for in handling utensil 21, said bail For convenience in packing a plurality of utensils 21 in one package, each receptacle .22 is constructed so as to be adapted to nest together in each other, each cover 23 and ball 29 having been removed, sa1d removed :covers and bails being adapted to be placed into the last of a nest of receptacles.

It is, of course, understood that although 26 of utensil 21 is to be adapted substantially to conform with the shape of the adjacent surface of stove body 1 associated therewith, otherwise the general shape and outline of said utensil may be varied as desired, the approximately rectangular general shape shown in the drawings being only by way of illustration.

Stove-body l is constructed of three flat plates 32, 33, and 34., plate 32 being hinged to plate 33zat 35, and plate 34 being hinged to plate 33 at 36, and the free edge of plate 34l-be1ng provided with a flange 37, bent at 1 0111: Walls ofplatcBd-iind adapted to overlap upon and bear against the adjacent outer surface of plate 32 adja-.

cent its free edge when plates 32 and 34 are swung toward each other upon their. hinged attachment 35 and 36 to form the triangular-shaped stove body 1 shown in Figs. 1, 2, 3, and 4. Grate 2 is triangular in shape,.

Figs. 4 and 6, and the free edges may be provided with a depending flanged portion 38 or the like for the purpose of strengthening same. The point of the triangular form of grate 2 opposite the hinged edge may be cut away as best seen at 39 in Figs. 4 and 6, so that when grate 2 is swung upwardly on hinges 6 against plate 33 in position for packing the stove, there will not be any parts protruding beyond the upper edge of said plate.

A plurality of pins 5 borne by the inner wall of plates 32 and 34 are each adapted to engage a corresponding opening 40 borne by grate 2 so that said grate may not only be supported thereby in operative position, Figs. 3 and 4, but, also, that the walls of the stove body 1 formed by swinging plates 32 and 34 toward each other may be held together firmly adjacent said grate.

In order to hold the walls of the stove body 1 more securely together, bail 18 may have one end-portion formed into a comparatively large open loop 41, Fig. 2, and by removably hooking said loop into appropriate holes 42 provided therefor in flange 37, plate 32, and plate 34, said plates are firmly held together.

In order to collapse the stove constructed as shown in the drawings, the cover comprising plates 13 and 14 having been removed and fitted together as shown :in Fig. 7, grate 2 may be swung upwardly against plate 33 as shown in Fig. 6, and then plates 32 and 34 may each successively be swung toward plate 33 to form a compact fiat package of portfolio shape, upon which plates 13 and 14, as packed together in Fig. 7, may be placed together with bail 18, making a package of little weight or bulk, adapted to be readily stowed away in a suit-case or the like. i

In operating the assembled stove and cooking outfit embodying the present invention, a fire upon grate 2 will, with the con sumption of very little fuel, quickly pro duce ample heat for all necessary cooking purposes, and not only may cooking be done upon the covered top of stove body 1 covered with perforated plates, imperforate plates, or with a combination of a perforc ted plate 13 and an imperforate plate 14, as shown in the drawings, but, also, by attaching one or more utensils 21 against the of said stove body, as shown in the to prepare an elaborate meal in camp.

outfit of the present invention provides the great advantage of a compact device occupy;

ing. very small spaceand adapted for cookingquantities of a large assortment of foods simultaneously witha minimum amount of labor and. the use of a small quantity of fuel, it having been found in practice that one firing of the stove is ordinarily suifici'ft ter stove body 1 has been thoroughly heated, the fire may be removed therefrom, and said member properly covered by the removable cover of this invention may be used as a Dutch oven for baking and the like.

By means of bail 18, the stove and cooking outfit while in operative use with fire therein and various utensils thereon and attached thereto with the contents may be carried from one place to another in a camp or the like without extinguishing the fire and without the necessity of removing the cooking utensils from the stove.

The stove and outfit embodying the present invention may be constructed of comparatively thin sheet metal, and when thus constructed, it has been found in practice that all parts cool quickly after the fire has been extinguished or has been removed from the stove, thus making it possible to pack the device ready for transportation without delay, which would be caused by waiting for heated parts made of heavy material to cool.

Many changes in the arrangement and combination of parts may be made without departing from the nature and spirit of the present invention.
